Variscope 20x - 40x 'Stereo Pro' Series Darkfield Gem & Jewelry Inspection Microscope

Great Features for High Quality Stereoscopic Imaging: This microscope is designed for high quality viewing of a wide range of specimens. This microscope is manufactured with an internally rotating dual 2x - 4x stereo objective made from premium ground optical glass. Used in conjunction with the included wide field 10x (23mm) stereo eyepieces, you can achieve magnifications of 20x and 40x right out of the box. We offer a range of optional eyepieces and objectives as well. With our optional 20x eyepieces, you can increase the magnification range to 40x & 80x. Threaded auxiliary objective lenses are also available in .5x, 1.5x and 2x powers. With these optional lenses you can use this microscope at 10x, 20x, 30x, 40x, 60x, 80x, 120x and 160x powers.

Ideal for Gem & Jewelry Inspection: This microscope is ideal for inspecting and grading gemstones and jewelry, including diamonds. The microscope comes with a gem and specimen tweezer clamp and a dark field condenser. The dark field condenser assures that any light emitted from the lower light source passes through the specimen for optimal viewing. That is, no light rays from the lower light source travel directly into the objective or your eye unless they pass through the specimen first. This enables you to view gemstones and other translucent objects without the visual distraction of ambient light entering your eye . . . only light that has passed through the gemstone will be visible to you.

Ultra-Comfort Ergonomic Microscope Design: This stereo microscope has ergonomic features to make your microscope viewing as comfortable as possible. The main microscope head swivels 360 degrees for viewing from any angle, and the head itself sits at a comfortable 45 degree incline. The eyepieces sit in a gemel type assembly, allowing for maximum flexibility in adjusting the interpupillary distance. The right eyepiece holder includes an independently controlled diopter focusing adjustment, and molded rubber eyecups are provided for your comfort. The focusing knob is on both the right and left side of the scope allowing for easy adjustment with either the right or left hand. Unlike many cheaper stereo microscopes, this model has an internal objective turret. This means you can switch objectives with a simple turn of a knob rather than having to rotate the entire objective turret. In addition, the entire microscope head mounts on a height adjustable base, allowing the entire scope head to be adjusted higher or lower to accommodate very large specimens.

Built-In Dual Halogen Light Source: Most of the 20x - 40x stereo microscopes available have cheap, low-grade lighting. However, this microscope has premium dual built-in infinitely variable halogen lighting. The upper and lower light sources are controlled independently. A unique feature of this microscope is that the upper light can be removed or aimed independently. This enables you to make fine lighting adjustments from above and below the specimen -- a premium feature not available in cheaper models. Spare halogen bulbs are included with your microscope.

Dust Cover and More! This microscope includes a plastic dust cover to keep your microscope in clean dust-free condition. The microscope comes with a frosted glass specimen holder and also a reversible black & white specimen plate.
